I have a wool high cut (bikini cut) cover in size C. DS is around 25 lbs and had a growth spurt, so I have it packed away for #2, one day. It is extremely soft wool (flannel or felt?) and the rainbow stitching is really cute. Kind of reminiscent of Nikky wool because it has the internal 'hammock' and gussets, but from what I can tell, the classic full cut cover seems almost identical to IV wool. It is a very high quality cover, I recommend it!
